On May 23-24, following the Days of the International Academy of Education held earlier this week, the General Assembly of the International Academy of Education took place at HSE University Moscow. The assembly brings together education researchers and experts from all over the world, and this is the first time that the biannual meeting was held in Russia. Over the course of two days, members discussed joint projects and publications and met newly inducted members who had the opportunity to introduce themselves and present their research. Members also took part in small group discussions on a variety of topics, including digital literacy and math education.

The results of recent study conducted by the NASA Lunar Reconnaissance Orbiter, the agency’s automatic interplanetary station, show the existence of a ‘permafrost’ near the poles of the Moon with a relatively high content of water ice (up to 5% by weight). It is believed that water ice could supply a life support system for the future Russian Lunar Station and that it could also produce hydrogen-oxygen fuel for flights into deep space.

The HSE Centre for Studies of Income and Living Standards studied the dynamics of the middle class and its behaviour with regard to paid services. The study was based on data drawn from the HSE Russian Longitudinal Monitoring Survey (RLMS-HSE) for the years 2000 to 2017, and the results were presented at the 20th April International Academic Conference hosted by HSE.

Observation of the rare B0s→μ+μ−Bs0→μ+μ− decay from the combined analysis of CMS and LHCb data

A joint measurement is presented of the branching fractions B0s→μ+μ−Bs0→μ+μ− and B0→μ+μ−B0→μ+μ− in proton-proton collisions at the LHC by the CMS and LHCb experiments. The data samples were collected in 2011 at a centre-of-mass energy of 7 TeV, and in 2012 at 8 TeV. The combined analysis produces the first observation of the B0s→μ+μ−Bs0→μ+μ− decay, with a statistical significance exceeding six standard deviations, and the best measurement of its branching fraction so far. Furthermore, evidence for the B0→μ+μ−B0→μ+μ− decay is obtained with a statistical significance of three standard deviations. The branching fraction measurements are statistically compatible with SM predictions and impose stringent constraints on several theories beyond the SM

One of directions of activity of the scientifically-educational centre "SPACE" created by the Moscow state institute of electronics and mathematics (technical university) and Space research institute of the Russian Academy of Sciences is discussed. The general statements of problems connected with working out of models of movement of asteroids and comets taking into account not gravitational indignations and construction of models for measurement of trajectories are considered. On a space vehicle orbit in a vicinity of libration’s points the traffic control model is discussed with application of a solar sail with operated reflective characteristics.
